Tab in Estimate to integrate my vendors' known pricing.

Also, since materials list are created in quote with labor, a tab with removable pricing for vendor specifics( or selection of materials for specific vendor) would be ideal. CSV files work good and can manually be created, but streamlining process would put the icing on the cake. If process is not feasible, at least integrate where estimate can be revised via CSV file without having to reinsert with all markups and all manually figured. If materials list/ purchase order can be created when put thru quickbooks integration that would be a great option as well.
